Bluetooth device do not get recognised

I am using Inspiron 1545 which has Dell Wireless 365 Bluetooth Module which is of broadcom.
When i try to install driver compatibility issue comes up. It doesnt proceed even though i have marked compatibility as windows 7 or vista too.
I have tried using the broadcom tool to detect the device and install the driver but that also fails to detect the module.
And when i use my second OS windows 7 bluetooth works flawlessly. So its only windows 8 not able to detect my hardware. I have also checked in device manager and there also it is not present.

Having the same problem (only on a Precision M6500) i finally found that the adapter is indeed detected, but only as a HID (Human interface device aka bluetooth mouse or keyboard).
You can see it in Device Manager under "Human interface devices" as 2 different "USB Human interface device"
Seems like the windows 7 driver switches the adapter to HCI mode after boot and is then detected as normal bluetooth, where as windows8 driver leaves it on HID mode (at POST time it has to be on HID mode to support bluetooth mice and keyboards).

One thing to try is go to Devices and Printers in the Control Panel, right click on your Laptop under Devices and select Troubleshoot. I did this for a Card reader that Device Manager couldn't find a driver for, and it found a solution by locating a driver itself and asking if wanted to download it. Its a clever troubleshooter.
